Autoosc is a Mathematica package for analyzing time-series of oscillatory signals, particularly those originating from biological/chemical systems.

Roughly, Autoosc takes oscillatory time-series as input and matches them to a large number of ordinary differential equations. It returns a list of equations that can produce signals similar to those input.
